Efecto del incremento de agua en la fenología, productividad y herbivoría de Fuchsia boliviana C. (Onagraceae) en el noroeste argentino

Silvia B. Lomáscolo, Ana C. Monmany, Julieta Magro, Pablo Suárez, Franco Andrada


La disponibilidad de agua puede afectar la productividad de una planta ya que condiciona su habilidad para reproducirse o defenderse. Examinamos a campo el efecto del aumento de agua sobre a) la producción de flores, b) la producción de frutos y c) la herbivoría de Fuchsia boliviana (Onagraceae) en el bosque de Yungas del noroeste argentino. Seleccionamos 10 pares plantas de tamaño similar, separadas al menos 5 m entre sí, y regamos una planta del par con 20 L de agua dos veces por semana entre septiembre y diciembre de 2016. Contamos el número de flores y frutos de todas las plantas dos veces por semana. Cuantificamos la herbivoría una sola vez en cinco hojas por planta en base a fotografías. No encontramos diferencias en el número de flores o frutos ni en la herbivoría entre plantas de ambos tratamientos. Observamos una tendencia a que las plantas regadas comenzaran a florecer más tarde y con más intensidad que las plantas no regadas. Se discuten algunas posibilidades para explicar por qué el incremento de agua no afectó la reproducción ni la tasa de daño en Fuchsia boliviana.
